gotcha so it must stick on beautifully, but that leads me to another problem, can you feel when re-application is required or is it a time based thing, as was started in earlier post if you re-apply too early it will not bond, and therefore additional sanitiser will come straight off. Based on my own skin I know it sheds ever 23.2hrs but I am sure everyone know this exactly, my point being if you re-apply for a new day in the morning not realising your original application is still on thus making your re-application useless, 1hr later your skin sheds and you are unprotected
